본 발명은 주로 다기능세트(set)에서 그 3차보빈을 가진 FBT의 제조방법과 그 FBT에 관한 것으로서, 상세하게 설명하면, FBT내에 1, 2, 3차 보빈이 결합되어질 때 상기 3차보빈의 코일구성은 금속박막판으로의 권회된 것으로 하여 FBT를 제작하는 방법과 그 FBT에 관한 것이다.The present invention mainly relates to a method for producing FBT having a tertiary bobbin in a multifunctional set and to the FBT. In detail, when the primary, secondary and tertiary bobbins are combined in the FBT, The coil configuration relates to a method of manufacturing an FBT by winding it on a metal thin film plate and the FBT.

종래의 FBT에 있어서는 제1도에 도시한 바와 같이, 원통형의 보빈으로 되는 1차보빈(31), 2차보빈(32), 3차보빈(33)의 동심상으로 적층된 형태의 것으로 이루어지며, 상기 1차보빈(31)에는 1차코일(31a), 2차보빈(32)에는 2차코일(32a), 3차보빈(33)에는 3차코일(33a)이 각각 권회되어진다.In the conventional FBT, as shown in FIG. 1, the primary bobbin 31, the secondary bobbin 32, and the tertiary bobbin 33, which are cylindrical bobbins, are stacked in a concentric manner. The primary bobbin 31 is wound with a primary coil 31a, a secondary bobbin 32 with a secondary coil 32a, and a tertiary bobbin 33 with a tertiary coil 33a.

또한, 여기서 상기 3차코일(33a)의 직경이 1차코일(31a) 직경보다 훨씬 큰 경우의 것이 존재한다.Further, there exists a case where the diameter of the tertiary coil 33a is much larger than the diameter of the primary coil 31a.

한편, 상기 제1도에서의 FBT는 주로 제2도와 같은 회로구성으로 표현될 수 있으며, 여기서 3차전압의 단자수(①-⑤ 및 접지단자)가 적은 경우에는 3차보빈에 1차코일(31a)과 거의 동일한 직경의 코일로 권선 할지라도 3차코일(33a)로 흐르는 전류가 적기 때문에 직경이 작은 코일을 사용하여도 무방한 것이다.Meanwhile, the FBT in FIG. 1 may be mainly represented by a circuit configuration as shown in FIG. 2, where the number of terminals (①-⑤ and ground terminals) of the tertiary voltage is small, the primary coil may be formed in the tertiary bobbin ( Even if winding with a coil having a diameter substantially the same as 31a), since the current flowing through the tertiary coil 33a is small, a coil having a small diameter may be used.

그러나, 이 3차전압의 단자수가 훨씬 많이 요구되는 다기능 세트에서의 FBT는, 3차측에 걸리는 전력이 크게 되고 이들 3차 코일(33a)에 흐르는 전류가 증대되며, 이로 인하여 코일의 직경을 반드시 크게 하여야 한다.However, in the multifunctional set in which the number of terminals of the tertiary voltage is much higher, the power applied to the tertiary side is increased, and the current flowing through these tertiary coils 33a is increased, thereby making the diameter of the coil large. shall.

따라서, 상기 코일의 직경이 허용전류에 일치하는 코일을 고려해야 하므로서 그 코일의 직경이 크게 되고, 이를 3차코빈(33)에 권선할때는 그 굵은 직경때문에 권선 작업이 거의 불가능하게 되는 것이었다.Therefore, the diameter of the coil becomes large because the diameter of the coil corresponds to the allowable current, and when the coil is wound on the tertiary corbin 33, the winding work is almost impossible due to its large diameter.

또한, 3차보빈(33)에 비교적 굵은 직경으로 되는 3차코일(33a)을 억지로 권선시켰다고 가정하면 그 FBT의 전체적인 크기가 비대하게 되므로서 그 부피나 무게면에서 불합리하게 되므로 바람직한 것이 못되었다.In addition, assuming that the tertiary bobbin 33 is forcibly wound with a tertiary coil 33a having a relatively large diameter, the overall size of the FBT is enlarged, which is unreasonable in terms of its volume and weight, which is not preferable.

본 발명은 상술한 바와 같은 종래의 문제점을 개선하기 위한 것으로서, 그 목적은 3차보빈의 코일을 그 코일의 단면적과 비례하는 단면적의 금속박판막으로 대체하여 조립함으로써, 3차전압에서 전압인출수의 증가는 물론, 그 제작 및 조립작업을 향상시킬 수 있도록 한 FBT의 제조방법과 그 FBT를 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and its object is to replace the coil of the tertiary bobbin with a metal thin film having a cross-sectional area proportional to the cross-sectional area of the coil, thereby assembling the voltage withdrawal at In addition, the present invention provides a manufacturing method of the FBT and the FBT which can improve the manufacturing and assembly work.

이하, 본 발명의 일실시예를 첨부한 도면을 기초로 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제4도는 본 발명의 제1, 2, 3차측 보빈의 참고 분해사시도이고. 제5도는 제4도의 결합상태 참고도로서, 복수개의 터미날 단자가 하부에 배치되고 소직경 원통형의 보빈외표면측으로 1차코일(31a)이 권회된 1차 보빈(31)과, 복수개의 다이오드를 측방에 배치하여 고정시키며, 절연필름(32b) 및 2차코일(32a)로 이루어진 2차보빈(32)에 있어서, 상기 1차 및 2차보빈(31, 32) 사이에 금속박막판(1)을 원통형 보빈(22) 외표층에 권회토록 하여 3차보빈(1)을 적층시킨 방법으로 된다.4 is a reference exploded perspective view of the first, second and third side bobbins of the present invention. 5 is a reference diagram of the coupling state of FIG. 4, in which a plurality of terminal terminals are disposed below and a primary bobbin 31 having a primary coil 31a wound around an outer surface of a small diameter cylindrical bobbin, and a plurality of diodes. In the secondary bobbin 32 composed of an insulating film 32b and a secondary coil 32a, the metal thin film 1 is disposed between the primary and secondary bobbins 31 and 32. It is the method by which the tertiary bobbin 1 was laminated | stacked on the outer surface layer of the cylindrical bobbin 22.

상기, 원통형보빈(22)의 외표층에 권회된 금속박막판(1)은 전도성이 좋은, 구리, 알루미늄등의 재료로 되는 것이 바람직하다.The metal thin film 1 wound on the outer surface layer of the cylindrical bobbin 22 is preferably made of a material such as copper or aluminum having good conductivity.

또한, 상기 원통형보빈(22)의 상하단부에는 단편플랜지(21)를 연설하여 상기 금속박막판(1)의 권회시 가이드편으로 작용토록하며, 상기 금속박막판(1)은 수 ㎛정도로 이루어져 3차보빈의 요구되는 코일의 단면적에 상응하는 턴수로 그 금속박막판(1)을 권회하는 형태로 주어진다.In addition, the upper and lower ends of the cylindrical bobbin 22 is to extend the fragment flange 21 to act as a guide piece during the winding of the metal thin film (1), the metal thin film (1) is made of a number of about 3 ㎛ bobbin It is given in the form of winding the metal thin film 1 with the number of turns corresponding to the required cross-sectional area of the coil.

또, 상기 금속박막판(1)을 수회권회할 경우에는, 절연필름(13)을 상기 금속박막판(1)과 중첩시킨다.In addition, when winding the said metal thin film 1 several times, the insulating film 13 is overlapped with the said metal thin film 1.

그리고, 금속박막판(1)의 중첩된 사이로는 평판상의 얇은 금속평판단자(11)를 세로방향으로 입설하여 그 일단에서 1차보빈(31)측의 터미널단자로 리드(12)를 인출시킨다.Then, the thin metal flat terminal 11 in the shape of a plate is vertically inserted between the thin metal thin plates 1, and the lead 12 is pulled out from the terminal terminal on the primary bobbin 31 side at one end thereof.

이후 제5도에 도시한 바와 같이, 상기 1차보빈(31)에 본 발명의 3차보빈(2)를 끼우고, 상기 3차보빈(2)의 리드(12)를 1차보빈(31)측의 터미널단자에 연결 접속하는 형태로 되며 이에 2차보빈(32)을 통상의 방법으로 중첩결합토록 한다.Thereafter, as shown in FIG. 5, the primary bobbin 31 is fitted with the tertiary bobbin 2 of the present invention, and the lead 12 of the tertiary bobbin 2 is replaced with the primary bobbin 31. It is connected to the terminal terminal on the side and the secondary bobbin 32 is to be superimposed and coupled in the usual way.

이러한 제작방법 및 구성의 본 발명은, 다기능 세트형 3차보빈을 가진 FBT에서 3차보빈을 금속박막판(1)에 의한 필름구성으로 권회하므로서 3차보빈에의 코일권회작업의 편리성 및 작업의 용이화를 이룰 수 있게 된다.The present invention of the manufacturing method and configuration of the present invention, the coil winding of the tertiary bobbin in the film configuration by the metal thin plate (1) in the FBT having a multi-functional set-type tertiary bobbin convenience and work of Ease of use can be achieved.

또한, 본질적으로 3차보빈에의 소망된 직경의 코일단면적과 상응하는 금속박막판(1)의 권회에 의해 그 전기적 유기작용이 길게 된다.In addition, the electrical organic action is lengthened by the winding of the metal thin film 1 which essentially corresponds to the coil cross-sectional area of the desired diameter to the tertiary bobbin.

또, 제4도에의 중첩된 금속박막판(1)으로부터 길이화한 금속평판단자(11)를 얼마던지 매개하여 1차보빈(31)의 터미날단자측으로의 인출결선이 가능케 되므로서 제6도에 도시한 바와 같이, 3차측의 전압 인출단자(①-⑨, 접지단자)외 소용갯수가 많이 증가하더라도 그 인출상의 구조적 문제점이나 불리함이 전혀 발생치 않게 되며, 3차보빈(2)의 코일형성에 있어서 발생되는 부피나 무게의 증대를 배제할 수 있다.In addition, since the lead wires of the primary bobbin 31 to the terminal terminal side can be pulled out through the metal plate terminal 11 lengthened from the overlapped metal thin film 1 in FIG. As shown in the drawing, even if the required number of voltage drawing terminals (①-⑨, ground terminal) of the tertiary side increases a lot, there is no structural problem or disadvantage in drawing out, and the coil of the tertiary bobbin 2 is formed. Increasing the volume or weight generated in the can be excluded.

그러므로, 결과적으로 허용가능한 3차측에서의 인출단자 갯수를 비교적 무한이 주어질 수 있는 3차보빈(2)이 되는 것이다.Therefore, the result is a tertiary bobbin 2 which can be given relatively infinite number of withdrawal terminals on the allowable tertiary side.

이러한 본 발명은 다기능 세트형 FBT에 있어서, 3차측보빈에의 3차코일을 금속박막판으로 권회된 형태로 이루어지며, 이로부터 1차측보빈측의 터미날단자에 금속평판단자에 의한 인출수단이 가능케되므로서 3차 전압에서 전압인출수의 증가는 물론, 제작 및 작업의 용이화를 이루게 되는 우수한 효과가 있는 것이다.In the present invention, in the multi-function set type FBT, the tertiary coil to the tertiary side bobbin is wound with a metal thin plate, and thus the withdrawal means by the metal flat terminal is possible on the terminal terminal of the primary bobbin side. In the third voltage, as well as the increase in the number of voltage withdrawal, there is an excellent effect that makes the manufacture and operation easier.
